Schëuermanńs kyphosis is usually observed with a mild idiopathic scoliosis, and there is parity between these two diseases. The aim of this work is to establish a hypothesis about the existence of a biomechanical causal relationship between Schëuermann's kyphosis and scoliosis. To achieve this, a literature review was conducted. A simple mechanical model of the passive thoracolumbar subsystem was created to support part of the discussion. This mechanical model describes the passive thoracolumbar subsystem under ideal conditions of equilibrium. After giving consideration to the system under these conditions, some of the geometrical changes that may be found in Schëuermanńs kyphosis are considered. Next, this work discusses the evolution of the spine, taking into account its relationship with stable equilibrium, which the passive subsystem tends toward. We hypothesized about the postural response of the body to compensate for possible situations of imbalance. In conclusion, it can be found that a change in the alignment of the spine may occur due to the postural adaptation of the body to an inadequate mechanical situation that may lead to scoliotic deformity of the spine.

The authors report 6 cases of thoracic disk herniations in patients with Scheuermann's disease. They underline the relationship between the neurological symptomatology and Scheuermann's disease by the herniation and evolution in their treatment by a new surgical approach.

Review
OBJECTIVE
To determine optimal proximal fusion levels for instrumented spinal fusion for Scheuermann kyphosis.
METHODS
We reviewed 86 patients (33 women) who underwent corrective instrumented spinal fusion for Scheuermann kyphosis. All patients had long-cassette upright lateral radiographs taken preoperatively, postoperatively, and at 2 years and the last follow-up. Demographic, radiographic, and surgical parameters were compared between patients with and without PJK.
RESULTS
PJK occurred in 28 patients (32%). The mean maximum Cobb angle was 85.8° ± 11.7° preoperatively, 54.8° ± 14.2° postoperatively, and 59.7° ± 16.8° at the last follow-up. Age and sex did not differ between the PJK and non-PJK groups (P > 0.05). The preoperative curve characteristics, fusion levels, and corrective ratio were similar in both groups (P > 0.05). The maximal Cobb angle at 2 years and the last follow-up significantly differed between the 2 groups (P < 0.05). The proportion of patients with the uppermost instrumented vertebra (UIV) at or above the proximal end vertebra (PEV) was similar in both groups (P > 0.05). The proportion of patients with UIV at or above T2 was significantly greater in the non-PJK group (P < 0.05). PJK was significantly associated with a C7 plumb line (C7PL)-sacrum distance ≥ 50 mm (P < 0.05).
CONCLUSION
PJK is the main cause of postoperative correction loss. Proper fusion-level selection can reduce PJK occurrence. We recommend having the UIV at T2 or above, especially when the C7PL-sacrum distance ≥ 50 mm.

Review
STUDY DESIGN
The design for this article is a case report.
OBJECTIVES
Reported is the case of a patient with Scheuermann's disease who experienced spastic paraparesis caused by multilevel disc herniations and intraspinal meningeal cyst occurring together.
SUMMARY OF BACKGROUND DATA
Although Scheuermann's disease is associated with disc degeneration and calcification, multilevel disc herniations causing neurologic deficit is exceedingly rare.
METHODS
A patient diagnosed with Scheuermann's disease was evaluated by laboratory tests and radiographs because of paresthesin in bilateral lower extremities.
RESULTS
Evaluation revealed a "cyst" that was separated from the proper subarachnoid space and a disc herniation.
CONCLUSIONS
Intraspinal cyst and multilevel disc herniations could coexist in Scheuermann's disease. Both could contribute to cord compression. Drainage of the cyst, anterior decompression of the disc herniations, and interbody fusion to stabilize the diseased segments produced good results after 2 years.

Scheuermann's juvenile kyphosis may be considered a form of vertebral osteochondrosis. Although the etiology remains unknown, the ultimate effect is a disorderliness of vertebral growth in the growth plate cartilage. The biomechanical effects of increased kyphosis on saggital plane deformity, especially in a growing child, serve to aggravate this deformity.

European Spine Journal : Official... Mar 2017To investigate the relationship between preoperative and postoperative spinopelvic alignment and occurrence of DJK/DJF. (Observational Study)
Observational Study
PURPOSE
To investigate the relationship between preoperative and postoperative spinopelvic alignment and occurrence of DJK/DJF.
STUDY DESIGN/SETTING
This was a retrospective observational cohort study.
PATIENT SAMPLE
The sample included 40 patients who underwent posterior correction of SK from January 2006 to December 2014.
OUTCOME MEASURES
Correlation analysis between the preoperative and postoperative spinopelvic alignment parameters and development of DJK over the course of the study period were studied.
METHODS
Whole spine X-rays obtained before surgery, 3 months after surgery and at the latest follow-up were analyzed. The following parameters were measured: maximum of thoracic kyphosis (TK), lumbar lordosis (LL), sagittal vertical axis (SVA), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lower instrumented vertebra (LIV) and LIV plumb line. Development of DJK was considered as the primary end point of the study. The patient population was split into a control and DJK group, with 34 patients and 6 patients, respectively. Statistic analysis was performed using unpaired t test for normal contribution and Mann-Whitney test for skew distributed values. The significance level was set to 0.05.
RESULTS
DJK occurred in 15% (n = 6) over the study period. There was a significantly lower postoperative TK for the group with DJK (42.4 ± 5.3 vs 49.8 ± 6.7, p = 0.015). LIV plumb line showed higher negative values in the DJK group (-43.6 ± 25.1 vs -2.2 ± 17.8, p = 0.0435). Furthermore, postoperative LL changes were lower for the DJK group (33.84 ± 13.86% vs 31.77 ± 14.05, p < 0.0001.) The age of the patients who developed DJK was also significantly lower than that of the control group (16.8 ± 1.7 vs 19.6 ± 4.9, p = 0.0024.) CONCLUSIONS: SK patients who developed DJK appeared to have a significantly higher degree of TK correction and more negative LIV plumb line. In addition, there may be a higher risk for DJK in patients undergoing corrective surgery at a younger age.

Review
Scheuermann's kyphosis is the most frequent structural kyphosis in adolescents. There are gaps in the knowledge of epidemiology, aetiology and treatment. There are strong genetic and mechanical factors in the aetiology. Treatment options depend on the cobb's angle measured and the skeletal maturity. Training and brace treatment yield good results for milder curves, while surgical correction is the most effective for severe curves > 70°. Indications for surgery are subject of debate as complications are not uncommon.
